SAP FC: time dipendent master data

Hi All,

I'm implementing the new SAP RDS for Solvency II on SAP FC.

I have a important question: Is it possible to have time dipendent master data?

For example

1. The period of the reporting ID is 06.2014
2. I upload a record with a fund with rating AAA (and period 06.2014)
3. I create another reporting ID with period 09.2014
4. I update the master data for the same fund that now have a new rating (BBB)
5. I upload a record for the period 07.2014 with the same fund

When I execute the report for the period 06.2014 I can't see the old rating (AAA) but only the last.

Is it possible to have the history of master data's changes?

Thank you in advance,

Matteo
